The bivalent mixing valve ESBE VRG 143 is made of dezincification resistant brass DZR. For easy manual operation the valves are equipped with non-slip knobs and end stops for an operation angle of 90°. The valve position scale can be turned over and rotated, allowing many different mounting positions. The scale located below the adjusting knob can be positioned arbitrarily along the heart of the mixing valve, depending on the valve orientation in the application.

Installation example

Příklady instalací

Function

The BIV valve has two inlets to which the heat sources can be connected either in parallel or in series. The primary, i.e. the low grade heat source should be connected to port 1 and the secondary to port 2. When no heat is needed, both ports 1 and 2 are closed. When heat is needed, the supply from port 1 is used as long as the required temperature can be maintained. When this is no longer the case the valve provides initially a mixed flow from ports 1 and 2. Finally port 2 is fully open and port 1 closed. (The function is like a 3-way valve but with two inlets instead of one.)

Service and maintenance

All major parts can be replaced or re-sealed - a seal kit or a complete refurbishment kit is available. In most cases it is not necessary to remove the valve from the application during servicing.
